The stone moroko (Pseudorasbora parva), also known as the topmouth gudgeon, [1] is a fish belonging to the Cyprinidae family, native to Asia, but introduced and now considered an invasive species in Europe and North America. The fish's size is rarely above 8 cm and usually 2 to 7.5 cm (0.79 to 2.95 in) long.
Abby Deneau points out a large patch of invasive knotweed on Tuesday, Aug. 2, 2022, at Grand Woods Park in Lansing. Michigan's invasive species watchlist includes information on several bugs ...
The state of Michigan defines an aquatic invasive species as "an aquatic species that is nonnative to the ecosystem under consideration and whose introduction causes or is likely to cause economic or environmental harm or harm to human health". [1] There are approximately 160 invasive aquatic species residing in Michigan. [2]
The economic impacts of invasive species can be difficult to estimate especially when an invasive species does not affect economically important native species. This is partly because of the difficulty in determining the non-use value of native habitats damaged by invasive species and incomplete knowledge of the effects of all of the invasive species present in the U.S. Estimates for the ...
This is a list of invasive species in North America.A species is regarded as invasive if it has been introduced by human action to a location, area, or region where it did not previously occur naturally (i.e., is not a native species), becomes capable of establishing a breeding population in the new location without further intervention by humans, and becomes a pest in the new location ...
Japanese knotweed is seen in flower. Yellowish-white flower spikes appear in August and September, making now the best time of year to identify and report occurrences of this invasive species.
A controlled study comparing six native fish species with the introduced (and invasive) eastern mosquitofish (Gambusia holbrooki) on consuming larvae of the common banded mosquito (Culex annulirostris) in Brisbane found that the empire gudgeon was as efficient at eating mosquito larvae as the eastern mosquitofish and is a good candidate for ...
Non-native invasive species can disrupt ecosystems because they do not have natural predators, or other ecological checks-and-balances. Thus, with less competition from native species, non-native populations can explode. [9] Invasive insects and pathogens have eliminated entire tree species from forests of the United States in as little as decades.
